The Great Divorce

This is the first C. S. Lewis I've read and from this first impression I'm not encouraged to read more. Although this is classified as fantasy, it's true genre is that of religious tract.

It starts with the pretext of a journey, ostensibly the final bus ride of the dead, and ends when the narrator awakes from a dream. Aside from this, there is almost no story, just a series of dialogs between the ghosts of the dead and the denizens of Heaven. The message is clear: People who are shallow, annoying, self-centered, those who love selfishly, who have the weaknesses and foibles that we all have, can't gain admittance to Heaven until they repent and believe. While this may appeal to deeply religious Christians, I found it far too preachy.
